The invention relates to the technical field of boiler exhaust valves, and discloses a boiler
exhaust valve capable of reducing liquid sloshing by utilizing air elasticity. The boiler
exhaust valve comprises a valve body, wherein a drain opening is formed in the top of the valve body, retaining blocks are fixedly connected to the interior of the valve body, a
piston is movably connected to the surfaces of the retaining blocks, a blocking ball is fixedly connected to one sides, away from the retaining blocks, of the
piston through a
piston rod, the surface of the blocking ball is movably connected with a compression mechanism, the lower portion of the blocking ball is movably connected with a clamping mechanism, and the lower portion of the clamping mechanism is slidably connected with an inflow opening. According to the boiler
exhaust valve, gas is discharged from an exhaust groove in the compression mechanism, at the same time, the condition of liquid oscillation inside the valve bodyis observed, the
contact condition of air holes and the blocking ball is controlled by rotating a rotating rod, and the speed of the
exhaust gas is indirectly controlled; after the part of air holesare blocked, the vapor outflow speed is slowed to cause the pressure inside the valve body to become large, and the oscillation liquid causes water molecules inside the valve body to be pressed underthe action of
high pressure, so that the effect of eliminating the liquid oscillation is achieved.
